射频识别技术是利用无线信道实现双向通信的一种识别技术.近些年来,射频识别系统的应用领域日益扩大,现已涉及到人们日常生活的很多方面,如电子路牌、高速公路收费、物流管理、产品跟踪等领域.在未来几年中,RFID技术必将逐步取代条形码技术成为EPC领域的主宰.这使得作为RFID系统关键部分的读写器的设计和研究变得十分紧要和迫切,RFID读写器的研究和发展对RFID技术的成熟和广泛应用具有个很高的实际价值.
论文首先介绍了RFID的背景以及RFID目前国内外的研究现状及发展方向,接着对RFID读写器系统的组成及相关工作原理做了介绍.通过对RFID读写器系统的构成、通信的具体分析,给出了系统的整体规划方案.本次试验主要通过RS232串口通信实现对标签信息的读取.

Answer 1

RFID is the use of two-way communication channel to achieve a communication.In recent years,the application of RFID system is growing.It has been involved in many aspects of daily life,such as electronic signs,freeway tolling,logistics management,product tracking etc.In the next few years,RFID will gradually replace barcode technology and become master of EPC field.As a vital and integral part of RFID system,RFID reader has received much attention,and their design is very urgent and significant,the research and development of RFID reader is of practical value for the RFID system.
In this paper,we introduce the background and development of RFID reader.Then we write the composition and principle.With analyzing the reader’s composing and communication.In this test,we can read the information of RFID tag with RS232.
